Why can't I process my payment through PayPal with AMEX?

I tried many times to pay my Shopify plan so customer will start buying products on my store but I was unable to process my payment thru PayPal using AMEX. This is the only payment method I have.

Hi there, @Anndreycan .

I can definitely understand this is important, let’s see if we can get this sorted for you. Can you tell me or even better yet show me a screenshot of the exact error you are seeing when you attempt to make payment? Can you tell me what country you are based in please? As this can be a factor in whether or not PayPal is available for billing.

Looking forward to your reply, thanks!
